Frequently Asked Questions
Does this work on iPhone, Android, and PC?
Yes. On mobile devices (iOS Safari and Android Chrome), it activates your rear camera automatically. On laptops and desktop computers, it connects directly to your webcam or lets you paste screenshots.
Is my camera video stream or uploaded photo stored anywhere?
No. All barcode and QR pattern decoding is executed completely on your device via client-side JavaScript. FreeQR does not transmit, store, or view your camera feed.
Why won't my camera turn on?
Ensure that you have granted Camera permissions to your browser. If you previously clicked "Block", click the lock icon in your address bar and reset the camera permission to "Allow". Also make sure your website is running over HTTPS.
